Patent number: 10049461Abstract: A motion evaluation system includes a marker member including a body part having a first surface and a second surface parallel to the first surface, a reference indication part indicating a center of the first surface, and a plurality of markers arranged on the first surface to be spaced apart from the reference indication part. The marker member is arranged on an object such that the reference indication part is arranged at a reference point of a first coordinate system. A plurality of cameras generate coordinate images by respectively photographing the markers. A first coordinate calculator calculates first coordinate values of the markers in a first coordinate system by using separation distances of the markers and a first distance between the first surface and the second surface, the separation distances and the first distance being previously stored.Type: GrantFiled: April 21, 2017Date of Patent: August 14, 2018Assignee: Samsung Life Public Welfare FoundationInventors: Youngyih Han, Wonjoong Cheon, Junsang Cho, Sunghwan Ahn, Dooho Choi

Publication number: 20120226134Abstract: A system for controlling a therapy machine is a method for controlling a therapy machine for irradiating radiation onto a patient whose body has been stabilized. The method acquires a video signal constituted by a plurality of pixels including information on the posture of the patient; converts the video signal to digital format, and generates video data including information on characteristic values of each of the plurality of pixels; and calculates, on the basis of the information, the number of pixels from among the plurality of pixels of which the characteristic values lie outside a predetermined range. Then, the therapy machine is controlled based on the calculated number. Thus, medical accidents due to inattention during observation by therapists may be prevented, and the accuracy of therapy through the therapy machine may be improved.Type: ApplicationFiled: November 12, 2009Publication date: September 6, 2012Applicant: SAMSUNG LIFE WELFARE FOUNDATIONInventors: Sang Gyu Ju, Youngyih Han, Yong Chan Ahn, Jin Sung Kim
